Some difficulties with hair materials
Particle edit - Comb, smooth, etc...

The greatest difference I can tell is probably caused by the lack of editing of the hair particles. They are currently pointing outard the faces normal (the default behaviour) like small spikes.



As you already noticed, the fur look quite short, but in my opinion reducing the lenght can't alone do the job. You'll need to bend it toward the skin by to combing the fur, in the right direction. Take for example the pokemon's forehead fur where you can clearly see that hairs are pointing upward.



Don't forget to add some variance to the children (e.g. with curl, wave, spiral... kink setting). In the following image you can see the same fur ball combed and with a Curl Kink of 0.002.
